Lightweight, great sun protection, well-made, versatile.Bought this to replace a heavier, similar styled hat. The Helios is very light, but well-made and does the job. Provides sun protection, water beaded up and ran off during a late-day shower, and was reasonably cool in warmer conditions. It would likely soak through in a real, prolonged rain, but the flexible brim also made it easy to flip my hood over for more protection. I bought it large enough that I could wear a thin fleece beanie underneath. The combination was pretty wind-proof and increased my warmth. The headband snugs up with a cordlock so I can adjust the size easily. I wore it constantly for several days and found it comfortable--though the cordlock in the back is noticeable

Lightweight and durable sun protectionI used to think this kind of hat was stodgy, like what a middle aged white guy wears to go fishing with blotches of sunscreen on his face. I was wrong. I bought this because I work in a field under the sun and needed something lightweight, durable, and with 360 degree protection from the sun. Check, check, and check. The Helios is light, comfy, adjustable, and stays in place. It doesn't feel strange on your head. It's relatively breathable, but no hat really succeeds at that when its hot out. When it gets dirty you can put it in the washer. When you're tossing it around or stuffing it in a pack you don't have to worry about it getting bent. And it doesn't look half bad, either. Pretty cool after all.

Good but UglyThe good news is that the Helios Sun Hat is the kind of hat I have been looking for. It has a light color, adjustable headband, adjustable chin strap, lightweight, firm brim, and is packable.

The bad news is that because of the prominent "OR" logo, total strangers will stop you and ask if your name is Orville Redenbacher. They will continue to mock you as they walk away. The logo will also make it very difficult to impress members of the opposite sex.

My response to the logo is to vow to wear the hat backwards so that the logo is centered Over my Rectum.

Awesome HatI have taken this hat everywhere from a week long on the AT in 200 F + temps (ok it was only in the 90's with sun, rain, and everything in between and I was definitely glad my girlfriend made me pick one up. Also have used it on long days in the canoe scrapping bottom on the Shenandoah and it protected my head..neck.. shoulders from the wrath of the giant orange in the sky. It packs down to next to nothing and when pulled out the brim pops right back in place.

Good hat bad strap connectionI like the hat very much. It is light weight and does exactly what I want- cover my sun sensitive head while I do yard work and golf! Only one negative, the chin strap immediately tore loose on one side the first time I used it. Since that was not very important to me, I just clipped off the other side and am happily continuing on. If one were ordering this hat to wear in windy country though, the poorly attached chin strap could be a real problem.

Great hat, great price!I love just about everything about this hat.,,,,The brim is not too floppy, not too stiff. Just right.,,,,The material dries quickly, is light and breezy, and resists UV rays from zapping your dome!,,,,The cord for cinching up when riding a philly, or if in the wind is greatly appreciated.,,,,This was a great purchase with absolutely no regret.,,,,Easy on the wallet, easy on the eyes, comfy, very light, very packable, and it protects. ,,,,

NICE HAT!I got this hat to protect my self from the sun while outdoors. Last time out fishing all day i got burned with just a ball cap on. This hat is really nice, the fit/finish is superb. The hat has got an adjustable strap in the band so it is customizable as far as how tight it fits your head and the chin strap will keep you from loosing it if it did happen to get blown off your head. I am very happy with the hat.

There are more expensive and cheaper hats out there, this one is good value.I just finished climbing Kili and doing a Safari in Ngorogoro Crater, two very different environments. This hat survived and performed great. In the sun, it kept the sun off my bald head and i didnt burn at all. On the mountain, it was very weather resistant and stayed on even in big winds (as long as the strap was used). After 4 weeks of use... i took it home, threw it in the wash and its as good as new!
